Information about Blow Off Valves

That signature psssshh isn’t just for show — it’s performance. Our range of blow off valves (BOVs) is built for turbocharged setups that demand boost control, throttle response, and attitude. Whether you're chasing that sharp vent-to-atmosphere sound or a stealthy recirc setup, we’ve got what your build needs.

From street cars to full-track monsters, these valves help prevent compressor surge and keep your turbo spinning hard and happy.

🌀 Vented, recirculating, and dual-port options
🛠️ Bolt-on fitments and universal kits available
🔥 Trusted brands used in tuned turbo cars worldwide
📈 Ideal for remapped, high-boost, or custom builds

Add performance, protect your turbo, and crank up the soundtrack — with our selection of performance blow off valves.
